The area for a circle with a diameter of 8 cm is 50.24 cm². The area of a circle with a radius of 3 cm is 28.26 cm². 50.24 - 28.26 =  21.98 cm. So the difference is 21.98 cm.

Find the roots of the equation x^2+2x+5=0
stiv31 [10]

Answer:

x = - 1 ± 2i

Step-by-step explanation:

we can use the discriminant b² - 4ac to determine the nature of the roots

• If b² - 4ac > , roots are real and distinct

• If b² - 4ac = 0, roots are real and equal

• If b² - ac < 0, roots are not real

for x² + 2x + 5 = 0

with a = 1, b = 2 and c = 5, then

b² - 4ac = 2² - (4 × 1 × 5 ) = 4 - 20 = - 16

since b² - 4ac < 0 there are 2 complex roots

using the quadratic formula to calculate the roots

x = ( - 2 ± \sqrt{-16} ) / 2

  = (- 2 ± 4i ) / 2 = - 1 ± 2i

four spheres of radius 6cm just fit inside a cylinder calculate the volume inside the cylinder that is empty leave your answers
Alekssandra [29.7K]

Answer:

The volume inside the cylinder is  1152\pi\ cm^3.

Step-by-step explanation:

Given : Four spheres of radius 6 cm just fit inside a cylinder.

To find : Calculate the volume inside the cylinder that is empty ?

Solution :

The volume of the cylinder is volume of 4 spheres.

The volume of sphere is V=\frac{4}{3}\pi r^3

The radius is 6 cm.

The volume of four spheres is

V=4\times \frac{4}{3}\times \pi\times (6)^3

V=1152\pi\ cm^3

Therefore, the volume inside the cylinder is  1152\pi\ cm^3.
